Summary of SB3669 (104th General Assembly, Illinois)

Purpose and intent

SB3669 proposes to strengthen and formally establish a district-wide multi-tiered system of supports (MTSS) for students. The core aim is to ensure that schools provide structured, evidence-based academic, social-emotional, and behavioral interventions, with ongoing data-driven decision-making and active engagement of parents/guardians in the MTSS process.

Key provisions and changes

Establishment and policy requirements

  • Each school district and its schools must create, maintain, and implement a policy for providing academic, social-emotional, and behavioral interventions within a multi-tiered system of support (MTSS).
  • MTSS is defined as a tiered process of instruction and support using differentiated strategies, an evidence-based curriculum/interventions aligned to State standards, ongoing progress monitoring with scientific, research-based instruments, and data-driven educational decisions based on student response to interventions.
  • The MTSS process must use a collaborative team approach.

Parent/guardian engagement and data sharing

  • The MTSS process must include engagement and regular communication with the child’s parent or guardian.
  • For students identified for additional support, districts must provide written notice to the parent/guardian about the use and purpose of the scientific, research-based intervention within MTSS.
  • Parents/guardians may participate in the collaborative MTSS team at the district’s discretion.
  • Parents/guardians must be provided with all data collected and reviewed by the district concerning the child in the MTSS or SRBI (scientific, research-based intervention) process.
  • The State Board of Education (SBE) may provide guidance and identify resources to facilitate parent/guardian engagement in MTSS.

Alignment with special education requirements

  • The bill clarifies that MTSS activities do not alter districts’ responsibilities to identify, locate, and evaluate children with disabilities who may need special education services under IDEA or applicable state/federal rules.

Specific statutory amendments

  • Section 27-1 (Areas of education taught; MTSS; discrimination) is amended to codify MTSS definitions, requirements, and parent/guardian engagement as described.
  • Section 14-8.02h is repealed (the meaning here is that the existing statute related to SRBI/MTSS processes is repealed and replaced by the MTSS framework described in the new Section 27-1).

Who is affected

  • Public school districts and their schools in Illinois will implement MTSS policies.
  • Students in need of academic, social-emotional, or behavioral supports (the MTSS-identified group) and their parents/guardians are directly affected through notification, involvement opportunities, and data sharing.
  • The State Board of Education; it may issue guidance and identify resources to support parent/guardian engagement in MTSS.

Procedural and timeline aspects

  • The bill was introduced February 5, 2026, and has progressed through committee and readings with scheduled dates in 2026 (second reading April 16, 2026; third reading anticipated April 28, 2026, per the action history).
  • It repeals an existing provision (Section 14-8.02h) related to SRBI/MTSS processes, replacing it with the comprehensive MTSS framework outlined in the new Section 27-1.
  • The act would take effect upon passage and any enforcement timeline would be set by the Legislature or implementing guidance from the SBE (not specified in the text provided).
